Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilization vanes for spray nozzles are expensive, difficult to install, and inefficient in high flow rate applications due to obstructions and complex geometries, while lower-cost stamped vanes suffer from performance hampering obstructions.
Innovation Solution
A bowtie-shaped stabilization vane with a large central passage and triangular side sections, manufactured via simple metal stamping, minimizes obstructions and friction, and is easily installable by compressing and springing back into place, ensuring laminar flow and high efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stabilization vanes use complicated geometries with welded joints to provide large unobstructed fluid passages, then fluid flow performance is improved, but manufacturing cost increases and installation difficulty increases
Solution Approach 1:
The patent changes the geometric parameters of the stabilization vane by using a simple curved profile with specific radius ratios (R1/R2 between 2:1 and 5:1) and angle configurations (15-45 degrees), allowing the vane to be manufactured via stamping while maintaining effective fluid flow performance through optimized dimensional parameters
2Productivity
If stabilization vanes use complicated geometries with welded joints, then fluid flow performance is improved, but installation time and labor intensity increase
Solution Approach 1:
The stabilization vane is designed as a single segmented profile that can be stamped as one piece and installed as one component, eliminating the need for multiple welded sections and reducing installation complexity while maintaining fluid flow performance
Solution Approach 2:
By optimizing the geometric parameters (curvature radii, angles, thickness) of the vane profile, the design achieves effective flow stabilization with a simple single-piece structure that installs quickly without requiring complex assembly procedures
3Ease of manufacture
If stabilization vanes are made with simple metal stamping to reduce cost, then manufacturing cost decreases, but obstructions in the center region increase reducing performance
Solution Approach 1:
The patent optimizes the stamping vane geometry by using specific parameter ranges: radius R1 between 0.5-2 inches, R2 between 0.25-1 inch, thickness 0.125-0.5 inches, and angles of 15-45 degrees, creating a profile that minimizes obstructions while maintaining structural integrity and flow performance
Solution Approach 2:
The stabilization vane employs curved surfaces with specific radius ratios instead of sharp edges or flat surfaces, creating smooth flow paths that reduce turbulence and obstructions while being manufacturable by standard stamping processes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bowtie-shaped vane reduces turbulence and friction, enhancing spray nozzle performance at high flow rates with minimal assembly effort and cost, while maintaining efficiency and ease of installation.
Implementation Method 1
measures need to be taken to straighten the flow out before it is discharged from the spray nozzle. Stabilization vanes are one such measure. Stabilization vanes are structures that are inserted into the body of a spray nozzle to direct and guide fluid flow as it passes through the nozzle body
Implementation Method 2
The stabilization vane includes a laminar flow passage extending along a centerline of the stabilization vane from an inlet end to an outlet end

AI summary
A spray nozzle assembly includes a nozzle body having an internal fluid passageway. A stabilization vane is arranged in the internal fluid passageway. The stabilization vane has a cross-sectional shape in a plane perpendicular to a longitudinal axis of the stabilization vane. The stabilization vane is formed from a single, continuous piece of material that is insertable in the internal fluid passageway. The cross-sectional shape of the stabilization vane has a center section defining a center passage through the stabilization vane that is arranged in a center of the internal fluid passage. The center section being flanked by a first side section and a second side section. Each of the first and second side sections being open to the center passage at a respective inner portion.
